Abstract: Restoration of ecological resource services from oil spills or chemical releases is a central component of natural resource damage assessments (NRDA) in the U.S. Equivalency analysis methods, particularly habitat equivalency analysis (HEA) and resource equivalency analysis (REA), are widely used methods for scaling compensatory restoration requirements. Although originally conceived for relatively modest habitat and/or short-duration injury, HEA is now widely used in service quantification and restoration scaling at large, complex NRDA sites. HEA can be viewed as a simplified alternative to a comprehensive ecosystem approach that requires more extensive primary data collection and differing assumptions.
